Dialog System:
What do I need to have for data?
- The dialog
- The choices/responses
- If it triggers anything else
- If the conversation should end

Guide for using this dialog system:
---DIALOG FILE FORMAT---

'{}' Hold file variables such as the name of the speaker.
'-' Indicates the start of a new dialog block
'_' Indicates a choice given after the previous dialog block is shown. Choices are limited to 4 per dialog block.
'[]' square brackets above a dialog block or choice hold parameters. These are outlined below in "DIALOG PARAMETERS".

EXAMPLE:

filename = Character's name

*In the file*

{
name="John"
}

# this is just a comment so it won't be shown

-Would you like to buy this item for 5 gold?
[next=sold]
_Yes please!
[next=notake]
_No thanks!

# if the vender sold an item we should give it to the player
[id=sold, req=gold take 5 > poorboy, end=true, checkpoint=allout, cmd=item g 0]
-Wonderful! It's all yours!

# if the player didn't want to take the item
[id=notake, end=true]
-Unfortunate... 
It's wonderful sword :(

# if the player didn't have enough gold for the item
[id=poorboy, end=true]
-Aww come back when you have enough gold.

# once the item is sold
[id=allout, end=true]
-Thanks again for buying that!
